IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 208,932, dated October15, 1878; application filed April 12, 1878.

To all whom 'it may concern Be it known that I, NICHOLAS SEIBERT, of SanFrancisco, in the State of California, have invented a certain new anduseful Improve ment in'Lubricators; and I hereby declare the followingto be afull, clear, and exact description of the same, reference beinghad to the drawings making part -of this speciication, in which- Figurel is a side elevation of the device, and Fig. 2 is a vertical section ofthe same.

My invention has for its object to provide a transparent medium to beinterposed between an oil cup or tank and the point to be lubricated, s0that the quantity of oil passing to the said point may be observed.

My invention consists in a transparent cone, within which the oil drops,in combination with certain other elements, as hereinafter more fullydescribed and claimed.

In order that those skilled in the art may make and use my invention, Iwill proceed to describe the manner in which I have carried it out.

In the said drawings, A represents a glass or other transparent hollowcone, placed between the oil-tank and the point to be lubricated, andresting on a rim, a, formed on a base, B, and surrounded by a metallichousing, C, which extends about halfway up the cone, and abuts against arib, b, on the cone A. Beneath the lower edge of the cone in rim a areholes h, which will allow any droppings in the cone to flow out and fillthe space between the cone and housing, so as to have any internalpressure on the cone transmitted to the housing. A pipe, D, conducts theoil from a tank to a small upright pipe, i, rising from base B withinthe cone, having its upper end curved and near the peak of the cone. Apipe, E, conducts the oil from cone A to the point to be lubricated.Both pipes, D and E, are provided with proper cocks d c. Pipe D isconnected with the oil-tank, (not shown,) and pipe E leads to the pointor points to be lubricated. The joints are properly packed, as seen at gh', to make them tight, and there is an elastic medium interposedbetween the glass cone and the rim, so as to avoid breaking the glass. l

The oil, passing from the tank or reservoir through pipe D, falls dropby drop from the mouth of curved pipe t' to the bottom of cone A, whenceit passes to the point to be lubricated through pipe E. As the oil dropsthe engineer can see how many drops per minute pass to thelubricating-point.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An independent transparent medium removed from the oil-cup, andinterposed between the oil cup or tank and the point to be lubricated,whereby the oil may be observed while being fed out, vas described.

2. The cone A, provided with openings h., base B, housing C, and pipet', in combination with pipes D and E, substantially as described.
